- FIG. 6 is a block diagram showing a circuit configaration of the mobile telephone.
- a radio signal transmitted from a base station is received by an antenna 11, and input to a receiving circuit (RX) 13 via a duplexer (DUP) 12.
- the receiving circuit 3 mixes the received radio signal with a local oscillation signal output from a frequency synthesizer (SYN) 14, thereby downconverting the signal into an intermediate-frequency signal.
- the receiving circuit 3 processes this intermediate-frequency signal by quadrature demodulation, and outputs a reception baseband signal.
- the frequency of the local oscillation signal generated by the frequency synthesizer 14 is designated by a control signal SYC output from a control unit 23.
- the reception baseband signal is input to a CDMA signal processing unit 16.
- the CDMA signal processing unit 16 includes a RAKE receiver.
- the RAKE receiver despreads a plurality of passes included in the reception baseband signal by using spread codes. The signals of these despread passes are synthesized after their phases are arbitrated. In this manner, reception packet data having a predetermined transmission format is obtained.
- This reception packet data is input to a compressing/expanding) unit (to be referred to as a compander hereinafter) 17.
- the compander 17 demultiplexes the output reception packet data from the CDMA signal processing unit 16 into media data by a multiplexer/demultiplexer.
- the compander 17 individually decodes these demultiplexed media data. For example, in a speech mode, audio data such as speech contained in the reception packet data is decoded by a speech codec. Also, if video data is contained in the reception packet data as in a videophone mode, this video data is decoded by a video codec.
- a digital audio signal obtained by the decoding process is input to a PCM coding unit (to be referred to as a PCM codec hereinafter) 18.
- the PCM codec 18 decodes, by PCM, the digital audio signal output from the compander 17, and outputs an analog audio signal.
- This analog audio signal is amplified by an amplifier 19, and output from a loudspeaker 20.
- control unit 23 reads corresponding audio contents from a memory unit 24.
- the read audio contents is decoded, amplified, and output from the loudspeaker 20 via the PCM codec 18 and the reception amplifier 19.
- a digital video signal decoded by the compander 17 is input to the control unit 23.
- the control unit 23 displays the digital video signal output from the compander 17 on the main display 5a via a video RAM. Note that the control unit 23 displays not only received video data but also video data of an image sensed by a camera (not shown) on the main display 5a via the video RAM.
- the compander 17 When the reception packet data is e-mail, the compander 17 outputs this e-mail to the control unit 23.
- the control unit 23 stores the e-mail in the memory unit 24.
- the control unit 23 reads the e-mail from the memory unit 24, and displays the read e-mail on the main display 5a.
- the sub-display 5b displays information indicating the operation mode of the apparatus, incoming call notification information, and information indicative of the residual amount or charged state of a battery 25.
- a speech signal of a speaker input to a microphone 21 in the speech mode is amplified to an appropriate level by a transmission amplifier 22, coded into a digital audio signal by PCM by the PCM codec 18, and input to the compander 17. Also, an output video signal from the camera (not shown) is converted into a digital signal by the control unit 23, and input to the compander 17. Note that e-mail formed by the control unit 23 is also input from the control unit 23 to the compander 17.
- the compander 17 detects the energy amount of the input speech from the digital audio signal output from the PCM codec 18, and determines a transmission data rate on the basis of the detection result. Then, the compander 17 codes the digital audio signal into a signal having a format corresponding to the transmission data rate, thereby generating audio data. Also, the compander 17 codes the digital video signal output from the control unit 23, and generates video data. The multiplexer/demultiplexer multiplexes these audio data and video data in accordance with a predetermined transmission format to generate transmission packet data, and outputs this transmission packet data to the CDMA signal processing unit 16. Note that when e-mail is output from the control unit 23, this e-mail is also converted into packet data.
- the CDMA signal processing unit 16 spreads the spectrum of the output transmission packet data from the compander 17 by using a spread code allocated to a transmission channel, and outputs the signal to a transmitting circuit (TX) 15.
- the transmitting circuit 15 modulates the signal having the spread spectrum by using a digital modulation method such as quadrature phase shift keying (QPSK).
- QPSK quadrature phase shift keying
- the transmitting circuit 15 synthesizes the modulated transmission signal with the local oscillation signal generated from the frequency synthesizer 14, thereby up-converting the signal into a radio signal. Then, the transmitting circuit 15 amplifies the radio signal to a high frequency so that the transmission power level designated by the control unit 23 is obtained.
- the amplified radio signal is supplied to the antenna 11 via the duplexer 12, and transmitted from the antenna 11 to the base station.
- the mobile telephone of this embodiment includes a television receiver (TV receiver) 30.
- the TV receiver 30 receives, e.g., a terrestrial television video signal via an antenna 31, and converts the received television video signal into a digital television video signal.
- the control unit 23 displays this television video signal on the main display 5a.
- the mobile telephone of this embodiment also includes an external memory interface 27.
- This external memory interface 27 has a slot for the insertion and extraction of a memory card 28.
- the video content data are read out from the memory card 28 inserted in the slot.
- the control unit 23 decodes and plays back the readout video content data, and displays the data on the main display 5a.
- a power supply circuit 26 generates, from an output from a battery 25, a predetermined operating power supply voltage Vcc, and supplies this voltage to the individual circuits. Note that the battery 25 is charged by a charging circuit (not shown).
- the memory unit 24 uses, e.g., an EEPROM or hard disk as a memory unit.
- the control unit 23 includes, e.g., a microcomputer (central processing unit [CPU]). As control functions according to the present invention, the control unit 23 has a state checking function 23a, TV activation control function 23b, and TV video display control function 23c.

Abstract
Description
- The present invention relates to a portable terminal such as a mobile telephone or personal digital assistant (PDA) and, more particularly, to a folding-type portable terminal which pivotally connects first and second housings via a hinge mechanism.
- The mainstream of portable terminals typified by mobile telephones is a so-called folding type mobile telephone obtained by connecting first and second housings via a hinge mechanism. Also, in this type of terminal, not only a terminal with its housings being open and closed from 0° to 180° but also that with a display being facing outside in a state wherein housings overlap each other via a hinge mechanism which is articulated or pivoted 360° have been developed. This type of terminal is described in Jpn. Pat. Appln. KOKAI Publication No. 2002-141984.
- Also, a portable terminal which includes a built-in television tuner to have a function of displaying received television video data on a display, and a portable terminal which has a function of playing back recorded data or video content stored in a recording medium such as a memory card or a hard disk have been developed. This type of apparatus allows the user to view a television program and playback the video content while mobile communication is off. Hence, the range of applications for the portable terminal increases.
- However, the conventional portable terminal having the above television reception function and the video content playback function generally has a mobile communication function serving as a main function, and the television reception function and the video content playback function serving as sub-functions. Hence, when the television reception function and the video content playback function are to be performed, the user must select these function menus on a menu window by a key operation, and this operation is very cumbersome.
- Accordingly, an advantage of an aspect of the present invention to provide a folding-type portable terminal which can easily and quickly activate a video display function such as a television reception function or a video content playback function without any key operation by a user, thus improving operability.
- To achieve the above advantage, one aspect of the present invention is to provide a folding-type portable terminal which pivotally connects a first housing having a display to a second housing via a connection mechanism can set a state of the first housing with respect to the second housing in a first state, second state, and third state. The first state is a state wherein the housings overlap each other with the display facing inside, i.e., a state wherein the housings are folded with the display being hidden. The second state is a state wherein the housings overlap each other with the display facing outside, i.e., a state wherein the housings are folded with the display being exposed. The third state is a state wherein the housings are open so that the display is exposed. In accordance with the aspect of the present invention, the portable terminal detects a change in state of the first housing with respect to the second housing. If it is detected that the stare has changed from the first or third state to the second state, a image signal is received or read out from a memory to automatically active displaying the video signal on the display.

- FIGS. 1A and 1B to FIGS. 5A and 5B are views showing the outline of a mobile telephone according to the embodiment of the present invention. In FIGS. 1 to 5, reference symbols A and B denote front and side views, respectively.
- This mobile telephone is a portable communication terminal obtained by connecting first and
second housings hinge mechanism 3. Note that the first andsecond housings - On the front of the
first shell 1, an input device andmicrophone hole 8 are formed. The input device includesdial keys 6,function keys 4,side key 7a, andTV key 7c. Theside key 7a and theTV key 7c are arranged on the side of thefirst shell 1. Thefunction keys 4 include a multifunction key having the functions of a transmission key, end key, scheduling key, clear key, and cursor keys. TheTV key 7c is used to activate a television reception function. - A
main display 5a and aloudspeaker hole 9 are formed on the front of thesecond shell 2, and asub-display 5b and a camera (not shown) are arranged on the back of thesecond shell 2. Each of themain display 5a andsub-display 5b includes a backlight on the back side of a liquid crystal display (LCD) panel. Themain display 5a is used to display all display data such as phone book data, television video data, camera video data, mail data, and pictorial information. Alternatively, thesub-display 5b is mainly used to display the pictorial information. - The articulated
hinge mechanism 3 has a function of pivoting thesecond shell 2 in the direction of an arrow A with respect to thefirst shell 1, and that of pivoting thesecond shell 2 in the direction of an arrow B with respect to thefirst shell 1. This articulatedhinge mechanism 3 can change the state of theshells - That is, FIGS. 1A and 1B show a state (first state) wherein the
shells main display 5a facing inside. FIGS. 2A and 2B show a state (third state) wherein thesecond shell 2 is pivoted in the direction of the arrow A to obtain a 160° open state with respect to thefirst shell 1 to expose thedial key 6,function keys 4, andmain display 5a. FIGS. 3A and 3B show a state (fourth state) wherein thesecond shell 2 is pivoted in the direction of the arrow B from the above third state to obtain a 90° open state. FIGS. 4A and 4B show a state (fifth state) wherein thesecond shell 2 is pivoted in the direction of the arrow A from the above fourth state to obtain a 90° open state. FIGS. 5A and 5B show a state (second state) wherein thesecond shell 2 is pivoted through 90° in the direction of the arrow B from the above fifth state, and then pivoted in the opposite direction of the arrow A to cause theshells main display 5a facing outside. - Also, the first and
second shells sensors 10a to 10d for detecting the state of theshells sensors 10a to 10d comprises, e.g., a magnetic sensor to output a detection signal in the state wherein the sensors are close to each other in a predetermined distance. Of thesensors sensors second shells sensors - The circuit of the mobile telephone is arranged as follows. FIG. 6 is a block diagram showing a circuit configaration of the mobile telephone.
- That is, a radio signal transmitted from a base station (not shown) is received by an
antenna 11, and input to a receiving circuit (RX) 13 via a duplexer (DUP) 12. The receivingcircuit 3 mixes the received radio signal with a local oscillation signal output from a frequency synthesizer (SYN) 14, thereby downconverting the signal into an intermediate-frequency signal. The receivingcircuit 3 processes this intermediate-frequency signal by quadrature demodulation, and outputs a reception baseband signal. Note that the frequency of the local oscillation signal generated by thefrequency synthesizer 14 is designated by a control signal SYC output from acontrol unit 23. - The reception baseband signal is input to a CDMA
signal processing unit 16. The CDMAsignal processing unit 16 includes a RAKE receiver. The RAKE receiver despreads a plurality of passes included in the reception baseband signal by using spread codes. The signals of these despread passes are synthesized after their phases are arbitrated. In this manner, reception packet data having a predetermined transmission format is obtained. This reception packet data is input to a compressing/expanding) unit (to be referred to as a compander hereinafter) 17. - The
compander 17 demultiplexes the output reception packet data from the CDMAsignal processing unit 16 into media data by a multiplexer/demultiplexer. Thecompander 17 individually decodes these demultiplexed media data. For example, in a speech mode, audio data such as speech contained in the reception packet data is decoded by a speech codec. Also, if video data is contained in the reception packet data as in a videophone mode, this video data is decoded by a video codec. - A digital audio signal obtained by the decoding process is input to a PCM coding unit (to be referred to as a PCM codec hereinafter) 18. The
PCM codec 18 decodes, by PCM, the digital audio signal output from thecompander 17, and outputs an analog audio signal. This analog audio signal is amplified by anamplifier 19, and output from aloudspeaker 20. - Note that when an audio playback mode is set, the
control unit 23 reads corresponding audio contents from amemory unit 24. The read audio contents is decoded, amplified, and output from theloudspeaker 20 via thePCM codec 18 and thereception amplifier 19. - A digital video signal decoded by the
compander 17 is input to thecontrol unit 23. Thecontrol unit 23 displays the digital video signal output from thecompander 17 on themain display 5a via a video RAM. Note that thecontrol unit 23 displays not only received video data but also video data of an image sensed by a camera (not shown) on themain display 5a via the video RAM. - When the reception packet data is e-mail, the
compander 17 outputs this e-mail to thecontrol unit 23. Thecontrol unit 23 stores the e-mail in thememory unit 24. In accordance with a display operation performed on theinput device 5 by the user, thecontrol unit 23 reads the e-mail from thememory unit 24, and displays the read e-mail on themain display 5a. Note that the sub-display 5b displays information indicating the operation mode of the apparatus, incoming call notification information, and information indicative of the residual amount or charged state of abattery 25. - A speech signal of a speaker input to a
microphone 21 in the speech mode is amplified to an appropriate level by atransmission amplifier 22, coded into a digital audio signal by PCM by thePCM codec 18, and input to thecompander 17. Also, an output video signal from the camera (not shown) is converted into a digital signal by thecontrol unit 23, and input to thecompander 17. Note that e-mail formed by thecontrol unit 23 is also input from thecontrol unit 23 to thecompander 17. - The
compander 17 detects the energy amount of the input speech from the digital audio signal output from thePCM codec 18, and determines a transmission data rate on the basis of the detection result. Then, thecompander 17 codes the digital audio signal into a signal having a format corresponding to the transmission data rate, thereby generating audio data. Also, thecompander 17 codes the digital video signal output from thecontrol unit 23, and generates video data. The multiplexer/demultiplexer multiplexes these audio data and video data in accordance with a predetermined transmission format to generate transmission packet data, and outputs this transmission packet data to the CDMAsignal processing unit 16. Note that when e-mail is output from thecontrol unit 23, this e-mail is also converted into packet data. - The CDMA
signal processing unit 16 spreads the spectrum of the output transmission packet data from thecompander 17 by using a spread code allocated to a transmission channel, and outputs the signal to a transmitting circuit (TX) 15. The transmittingcircuit 15 modulates the signal having the spread spectrum by using a digital modulation method such as quadrature phase shift keying (QPSK). The transmittingcircuit 15 synthesizes the modulated transmission signal with the local oscillation signal generated from thefrequency synthesizer 14, thereby up-converting the signal into a radio signal. Then, the transmittingcircuit 15 amplifies the radio signal to a high frequency so that the transmission power level designated by thecontrol unit 23 is obtained. The amplified radio signal is supplied to theantenna 11 via the duplexer 12, and transmitted from theantenna 11 to the base station. - The mobile telephone of this embodiment includes a television receiver (TV receiver) 30. The
TV receiver 30 receives, e.g., a terrestrial television video signal via anantenna 31, and converts the received television video signal into a digital television video signal. Thecontrol unit 23 displays this television video signal on themain display 5a. - The mobile telephone of this embodiment also includes an
external memory interface 27. Thisexternal memory interface 27 has a slot for the insertion and extraction of amemory card 28. Under the control of thecontrol unit 23, the video content data are read out from thememory card 28 inserted in the slot. Thecontrol unit 23 decodes and plays back the readout video content data, and displays the data on themain display 5a. - A
power supply circuit 26 generates, from an output from abattery 25, a predetermined operating power supply voltage Vcc, and supplies this voltage to the individual circuits. Note that thebattery 25 is charged by a charging circuit (not shown). Thememory unit 24 uses, e.g., an EEPROM or hard disk as a memory unit. - The
control unit 23 includes, e.g., a microcomputer (central processing unit [CPU]). As control functions according to the present invention, thecontrol unit 23 has astate checking function 23a, TVactivation control function 23b, and TV videodisplay control function 23c. These functions are implemented by allowing the microcomputer to execute programs. - The
state checking function 23a checks the state of the first andsecond shells sensors 10a to 10d. For example, on the basis of the detection signals from thesensors state checking function 23a checks whether the state of the first andsecond shells sensors state checking function 23a checks whether the state of the first andsecond shells - The TV
activation control function 23b includes manual and automatic activation modes as a TV activation mode to alternatively set these modes in accordance with the user's selection. When thestate checking function 23a determines that the state of theshells TV receiver 30 is automatically activated. - When the television video signal received by the
TV receiver 30 is to be displayed on themain display 5a, the TV videodisplay control function 23c selects a full-screen or partial-screen display mode on the basis of the shell state check result obtained by thestate checking function 23a. For example, when the state of theshells display control function 23c selects the full-screen display mode. The full-screen display area of themain display 5a is set as a television video display area to display the television video signal on this full-screen display area. In this case, the display direction of the television video signal is set so that the main scanning direction of the signal is the long-side direction of the full-screen display area of themain display 5a. - Alternatively, when the state of the
shells display control function 23c selects the partial-screen display mode. A TVvideo display area 51 is set at the center in the vertical direction of themain display 5a, and the television video signal is displayed on this TVvideo display area 51. In this case, the display direction of the television video signal display is set so that the main scanning direction is the short-side direction of the full-screen display area of themain display 5a. Additionally, additionalinformation display areas main display 5a. The pictorial information and guide information are displayed in the additionalinformation display areas - Next, the reception/display operation of the television video signal performed by the mobile telephone as described above will be described. FIGS. 7 and 8 show flowcharts showing a control procedure and control contents by the
control unit 23. - In the state (the first state shown in FIGS. 1A and 1B) wherein the first and
second shells main display 5a facing inside, thecontrol unit 23 monitors the opening operation of theshells step 8a on the basis of the detection signals from thesensors - Assume that the user opens the first and
second shells shells sensors step 8b, thecontrol unit 23 checks whether the incoming call notification operation is performed. If the incoming call notification operation is performed, thecontrol unit 23 determines that theshells - In contrast to this, if the incoming call notification operation is not performed, the
